Ah ok, I’m not using Home Assistant Cloud at all, so can’t help you with that.
I just bought a Google Home Mini and started using that as my TTS speaker, which works fine. No problems at all with SSL.
I’m not using my Logitech Squeezebox speaker at the moment, since it still doesn’t work with SSL. I would still love to use it though, so that I can broadcast to both my Squeezebox and Google Home Mini. Really hoping someone has a solution.
